VEHICLE-AXLE AND Box.

SPECIFICATION forming part of Letters Patent No. 364,333, dated June '7,1887.

Application filed December 8, 1856. Serial No. 252L028: (No model.)

To all whom it may concern:

Be it known that I, ANTON BRAUN, of Jersey City, in the county of Hudsonand State of New Jersey, have invented a new and useful Improvement inVehicle-Axles and Axle- Boxes, of which the following is aspecification.

My invention relates to those axles in which the wheel is retained uponthe axle by the engagement of the axle-box with the axle near its innerend, as distinguished from those axles in which the wheel is held inplace by a nut applied at the extremity of the axle-arm.

The invention consists in novel details in the construction of the partswhich embody my invention, and in the combinations of such parts, whichare particularly hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an axial section of a wheeLhuband axle-box and a side view of an axle-arm embodying my invention, andFig. 2 is a transverse section of the axle and an end view of the innerend of the hub.

Similar letters of reference designate corresponding parts in bothfigures;

A designates the axle or axle'arm, of which I have here represented butlittle more than the journal portion, and B designates an axlebox, whichis secured in the ordinary or any other suitable way in the hub O, andwhich is fitted to the journal of the axle A.

In this example of my invention the axle arm or journal is somewhattapered toward its outer end, and the axle-box is bored to acorresponding taper. Immediately at the inner end of the taper journalportion of the axle is a fixed or integral collar, 1), and at this endthe axle-box is closed bya cap, B, which may be secured in place at theinner end of the axle-box by screws 1). Any number of screws may beemployed, four only being here shown. 1

Immediately inward of the fixed collarb the axle A has a short cylindrieportion, A, and the cap B is bored to fit this cylindric portion, andinward of such cylindric portion A the axle A may be of ordinary squareor rootangular form.

In the inner end of the axle-box B is formed a rabbet or chamberedspace, Z1 which is of sufficient diameter to receive the integral collarb of the axle A, and upon the outer side of this collar, and between itand the bottom of the rabbet or chamber N, is a packing-washer, c, whichmaybe of leather or other suitable packing material,aud which is ofsubstantially the same diameter as the collar. The inner face of thecollar 1) is substantially flush with the inner end of the box, and theinner end of the .box is substantially flush with the inner to end ofthe hub G, and upon the inner side of the fixed collar 1) is a secondpacking-washer,

c, which may be of leather, or, if desired, of metal, and which isinterposed between the cap B and the collar b, and is clamped and 55held in place between the cap B and the inner end of the box, therebyforming an airtight joint. It will be observed that the ta per journalportion of the axle extends immediately from the collar 2) to its outerend, the journal having a continuous and uninterrupted taper between itsouter end and the collar 0. The axle-box B, which is tapered internallyto fit the journal portion, is constructed in the same manner, and thetapered bore of the axle- 7 5 box extends from its outer end clear tothe bottom of the rabbet or chambered space b".

By means of the fixed collar b fitting within the chamber or rabbetedrecess at the inner end of the axle-box B, the axlebox and wheel aresecurely held against any sliding movement on the axle, and thepacking-washer c prevents leakage of oil from the axle-box, while thepacking or washer 0, in addition to its function in preventing leakage,forms a part which may be readily renewed, and which takes the wear dueto end-play of the axle in the box.

As here represented, the journal portion of the axle A extends entirelyto its outer end and the axle-box B projects slightly beyond the outerend of the axle A, and is closed by a cap, B or analogous plug, in orderto form a closed oil-chamber, D, at the outer end of the axle. The cap Bmay be provided with 5 a fillinghole closed by a plug, (Z, and wheneverdesired said plug may be taken out and a proper quantity of oil may besupplied to the chamber D.

In order to provide for the free lubrication of the axle-journal A fromthe closed oil-chamber D, I have represented the axle-box B as providedwith grooves b in its bore. These grooves b are, as here shown, atdiametricallyopposite points, and as they are brought successively tolowermost position by the turning of the wheel they convey oil to thebearing-surfaces of the axle-box and axle.

I am aware that axle boxes and j ournals have been made with taperbearing-surfaces,and that a closed oil-chamber has been provided in thebox by a cap screwed upon its outer end, and that a wheel has been heldin place on the axle by a collar on the axle, which is confined betweenthe axle-box and a cap or plate secured to its inner end. I therefore donot claim, broadly, any of these features, but desire to restrict myinvention to the particular combination of parts above described andshown in the drawings as a whole, whereby I produce an axle and axle-boxpossessing advantages which no axle or axle-box known to me has had.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination, with hub O, of the box B, extending the entire lengthof the hub, and having secured upon its outer end the cap B, forming aclosed oil-chamber, D, the box having at the inner end the rabbet orchambered space 12 the axle A, having an integral collar, b, received inthe rabbet b", and the outer face of which is substantially flush withthe inner end of the box, and having a straight taper journal extendingoutward from the collar and fitting the tapered bore of the box, thewasher c, of substantially the same diameter as said collar, fittedbetween it and the bottom of the rabbet b, the cap B, closing the innerend of the box around the axle and secured by screws 1) directly to thebox, and the washer c, hearing against the inner face of the collar b,and held in fixed position between the cap and box by the screws 1), allsubstantially as herein described.

ANTON BRAUN.
